Abstract

In recent years, there has been a gradual decrease in the available water supplies. According to the available data, India, China, and Nigeria are the top three nations in which a high number of people are killed as a direct result of water pollution each year. Pollution of water can have detrimental effects not only on human health but also on the environment and the economy. In addition to this, it may also influence climate change, which, because of an increase in water level, may result in adverse weather conditions. The beverage industries in Malaysia are one of the primary contributors to the country's problematic water quality. Melaka is not immune to any of these issues; it has also been affected. The contamination that is taking place in the Sungai Melaka right now is responsible for the loss of fish diversity. The administration of Melaka state has carried out several initiatives, including the enforcement of laws, the regulation of water resources, and the dissemination of religious and moral teaching regarding the significance of rivers. On the other hand, the execution of such measures has not resulted in a reduction in the amount of water that is contaminated. The problem has reached a higher degree, and the gravity of the situation has increased as a result. Considering this, research and identification of the primary pollutants released by the primary sources of pollution should be carried out, particularly regarding the spatial variation that occurs in the Sungai Melaka. During this investigation, a Hydro Quality Survey System, also known as a HydroQS device, will be put into operation. The PA-12 Nylon powder, FS3300PA, will be utilized as the best selection of material. Because it is compatible with the SS402P SLS 3D Printing machine, which has been chosen for printing the HydroQS housing, PA-12 has been selected as the material to use. In this investigation, a field test will be conducted to investigate the mechanical properties of aged FS3300PA. Additionally, the dimension stability of sintering samples will be measured. The purpose of this study is to evaluate the HydroQS housing based on the sample shape that will be submitted to the 50KN Universal Tensile Machine (UTM), and the sample shape will be tested in Sungai Melaka. It is anticipated that the HydroQS housing that will be manufactured will have a low drag coefficient, high strength, and low weight, and will satisfactorily address and fulfill all Perbadanan Pembangunan Sungai dan Pantai Melaka (PPSPM) issues and requirements.
